The stale air exhaust system is accomplished by the posi-

tive pressure created in the furnace ducting. The air

During a defrost cycle, the HRV may produce some con-

densation. This water should flow into a nearby drain, or

be taken away by a condensate pump. 

The HRVcabinet has  prepunched holes for the drain (see

below). Insert the drain spout through the hole in the drain

pan. Do not forget the “O ring” which seals each spout to

the pan. REMEMBER TO HAND TIGHTEN ONLY 

the

washer and lock nut which hold the drain spout in place.

Construct a P-Trap using the plastic tee connector. Cut

two lengths of hose and connect each piece to an end of

the “T” fitting, then connect the other ends to the two drain

spouts. Position the "T" fitting to point upward, andconnect

the drain line. Tape or fasten base to avoid any kinks. This

creates a “trap” which will hold some condensate and pre-

vent odours from being drawn up the hose and into the

fresh air supply of the HRV.

A well designed and installed ducting system will allow the

HRV to operate at its maximum efficiency.

Always try to keep duct runs as short and straight as pos-

sible. See Installation Diagrams for various installation

options.

The inner and outer liners of the flexible insulated duct

must be clamped to the sleeve of the weather hoods (as

close to the outside as possible) and the appropriate port

on the HRV. It is very important that the fresh air intake

line be given special attention to make sure it is well

sealed. A good bead of high quality caulking (preferably 

silicone sealant) will seal the inner flexible duct to both the

HRV port and the weather hood prior to clamping with a

large zip tie.

To minimize air flow restriction, the flexible insulated duct

that connects the two outside weather hoods to the HRV

should be stretched tightly and be as short as possible.

Twisting or folding the duct will severely restrict air flow.

See below for the recommended connection of flexible

insulated ducts to the the outside weather hoods and the

HRV.
